Answer from Lunka about Pieter
Lunka says their dad never gives up, insisting he will get them out and that Brencis will not kill them; he speaks with fellow prisoners down there — Vladimir-like people whose companions will liberate them all, sometime soon.
But she confides, asking Coen not to tell Dad, that she sometimes hears him weep — after the blood-taking or the shouting at Mirto — and that he says strange things about Coen which she refuses to believe: he is not like them, he is not.
